1CPU cooling APIs How To 2=================================== 3 4Written by Amit Daniel Kachhap <amit.kachhap@linaro.org> 5 6Updated: 12 May 2012 7 8Copyright (c) 2012 Samsung Electronics Co., Ltd(http://www.samsung.com) 9 100. Introduction 11 12The generic cpu cooling(freq clipping) provides registration/unregistration APIs 13to the caller. The binding of the cooling devices to the trip point is left for 14the user. The registration APIs returns the cooling device pointer. 15 161. cpu cooling APIs 17 181.1 cpufreq registration/unregistration APIs 191.1.1 struct thermal_cooling_device *cpufreq_cooling_register( 20 struct cpumask *clip_cpus) 21 22 This interface function registers the cpufreq cooling device with the name 23 "thermal-cpufreq-%x". This api can support multiple instances of cpufreq 24 cooling devices. 25 26 clip_cpus: cpumask of cpus where the frequency constraints will happen. 27 281.1.2 void cpufreq_cooling_unregister(struct thermal_cooling_device *cdev) 29 30 This interface function unregisters the "thermal-cpufreq-%x" cooling device. 31 32 cdev: Cooling device pointer which has to be unregistered. 33
